Ping G Irons 4-PW,UW w/Graphite Shafts - Red Dot
Increases ball speed by 1.25 mph for distance with control, resulting in an average of 5 yards additional carry with a higher max ball height and steeper landing angle compared to G30 iron.
COR-Eye structure provides for a thinner face (32%), resulting in 4x face bending compared to G30 iron at peak deflection. The simultaneous activation of the sole, face and top rail creates a diving-board-like effect, springing the ball off the face at faster speeds.
HYPER 17-4 STAINLESS STEEL
Enables the COR-Eye technology design to function by allowing for a thinner face which produces faster ball speeds for more distance.
A six-hour total heat-treating process results in a 40% stronger material. 1.5 hours @ 1040°C in vacuum furnace aligns the grain structure, followed by the strengthening process for 4 hours @ 550°C (slow, air cool).
CONCEALED CUSTOM TUNING PORT
Positions the CG .015 " deeper and helps raise the MOI (5% top/bottom, 1.5% heel/toe) for more forgiveness, higher launch and tighter dispersion.
The cavity structure houses the concealed Custom Tuning Port that connects to the sole for the first time, creating a deeper CG and allowing for more weight on the toe and hosel region. Each iron's center of gravity is moved lower and farther back to increase the moment of inertia for extreme forgiveness and higher-launching results.
